Green onions should have a high yield, how to grow green onions to achieve high yield?

The white plant height of the long shallot, the uniform length and thickness of the white onion, and the high yield, the short green onion white onion white white is short and thick, in contrast, in the same area, the long green onion white variety has a higher yield than the short green onion white variety. According to the local planting habits and planting season (mostly spring and autumn), you can choose heat-resistant or cold-tolerant disease-resistant varieties. That is, the root of the green onion is long and thick is the most fundamental, if you want to make the root of the green onion long and thick, you have to give the green onion a long and thick growth environment, that is, to turn the land deeply, so that the land is soft, the green onion can grow long and thick, deep over the land, <>

Choose soil with loose soil, fertile soil and good drainage, and cannot rotate with onions, garlic and other crops to avoid yield reduction. It can be planted in fields where corn, sweet potatoes, soybeans and other fields have been planted. The choice of land, land preparation for furrowing, generally formed wide rice, the reason is that many green onion growers are only partial to the yield of green onions, the quality of green onions does not pay much attention to the final income, the green onion market has never lacked supply and demand of green onions, and some high-quality such as green onion white length, thickness, good taste of green onions ** has been firm.

Green onions can be planted at least twice a year. For the first time, you can choose to raise seedlings in June-July, plant them around September, and go on the market in March-April of the following year. The second time you can choose to raise seedlings in September, plant them in March-April, and market them in July-August.

Note that in the planting process, it must be reasonably densely planted, and deeply planted and covered. Generally, the green onions planted in our own vegetable gardens in our rural areas are first raised and then transplanted and planted. Green onion seeds should be sprouted.

You can soak the seeds with more than 50 warm water for half an hour, and stir when soaking the seeds, so that the seeds are fully absorbed by the water.

Choose the right land and grow good food. Because green onions are afraid of waterlogging and drought, it is necessary to choose a plot with good drainage, so it is recommended to choose loose sandy loam soil with high terrain and deep soil layer, and it is best to have not planted onions and garlic before. If it is the kind of land that has been planted for several years, it will almost be lost.

It should be watered and fertilized in a timely manner, and at the same time, it should also do a good job in the management of water and fertilizer, and it should also ensure sufficient light and suitable temperature, and it should also be sprayed in time to do a good job of pest control.

First of all, we should choose moist and fertile soil, and we should also choose high-yielding, pest-resistant seeds, and secondly, when planting, we should disinfect the land, and we should also pay attention to fertilization and watering, and pay attention to the prevention and control of pests and diseases, so that green onions can be highly productive.

Try to choose sandy loam soils. The quality of this soil is very good, so the green onions can get a good yield and the quality is quite high.

1.Autumn planting timeIt is planted in early to mid-September in the autumn of the first year, and planted in early to mid-May of the following summer, so it can be obtained before winter and can be cultivated in kilns or in the open field.

Generally in the early spring planting, and to carry out after the soil thaws, it can be used as a green onion supply before the arrival of the hot summer, after the green onion is planted, you can choose the dry onion or furrow onion obtained at the beginning, and can also be used as a wintering horn onion or seed plant.

It is mostly planted from mid to late July to early to mid-August, so it is also called Fu onion. At the beginning of wintering, the main stem is relatively large. It is easy to carry out the whole process of vernalization, it sprouts early in the next spring, and can quickly sprout and flower, so it is generally sold after the horn onion.

As a green onion planted in all seasons, it is best to choose a cold tolerant one. Drought. High temperature resistance. Adaptable. The green onion root is long. Species that do not tassel, such as Chinese giant onions. Zhangqiu green onion (high leg white) or regional farmhouse variety whip green onion.

1.Plough early, plant early

Reasonable dense planting is an important experience gained from many years of planting, and the production of early planting of onions is significantly higher than that of late planting. In addition, reasonable dense planting is the key countermeasure for high-quality and stable yield of green onions, and the general plant spacing is 4 6 cm, and the row spacing is 25 30 cm.

2.Soil weeding should be done immediately

Prevent root rot caused by waterlogging and improve the aeration of the soil, and the shallot is planted at a time when the temperature is high. When there is a lot of precipitation, there are many kinds of wild grasses, so we must hoe the grass immediately to avoid grass shortage; The moon is the period of concentrated precipitation in the north, which is easy to cause shallots to soak. Scorch.

In addition to doing a good job in draining and storing water, it is also necessary to break the surface moisture early, so that the rhizomes of shallots can carry out a variety of normal theme activities.

3.Base fertilizer topdressing should be appropriate

Generally, the first fertilizer is carried out after the cold dew, according to the conventional fertilizer situation, about 2000kg of fertilizer is needed for 1 mu, or 200kg of peanut bran, plus 20kg of urea solution. Until the second fertilization is carried out after the summer heat, about 15 kg of urea solution is required for this fertilizer.

In the end, it is to look at the growth of green onions, if the leaves of green onions are thinner, and there are more mixed barbs, then we must also top dressing appropriate potassium fertilizer. Moreover, in each growth of the green onion, I add chemical fertilizer appropriately and fill the nutrients needed for the growth of green onion.

We all know that now for many farmers, they need to learn a lot of precautions when planting each crop, and now many people want to have high yield when planting green onions, but some people will have such questions, that is, how to manage the planting of green onions to achieve high yield? For this problem, in my opinion, the first thing should be reasonable fertilization, and the second is to prevent pests and diseases.

1 Proper fertilization

In our real life, in fact, when planting each kind of crop, we need to apply a certain fertilizer, because many times these plants are far from enough to absorb those nutrients from the land, so when we see that the leaves of these green onions are relatively yellow, we can reasonably apply a certain fertilizer to them. This can provide them with some nutrients for their growth.

2. Prevent pests and diseases

In the process of planting green onions, sometimes it is likely to suffer from this situation, this phenomenon is very common in our real life, so when we see such a phenomenon, we should promptly call a certain pesticide to the green onion, some pesticides themselves are to prevent and control the invasion of pests and diseases. For example, pesticides. These are some of the high-end technologies that are available today.

And it is also targeted to crops.

Therefore, in ordinary life, we should pay more attention to this aspect of the problem, for everyone, when we are planting these crops, we should observe some of his current situation, if there is any abnormal phenomenon, we should take some effective measures to prevent it in time. So as not to bring us certain economic losses, because in many cases, if there is such an invasion of pests and diseases, it is likely to lead to a reduction in yield, and will seriously affect his normal growth. That's it for some of my knowledge on this issue.

It is divided into three stages of management: the first stage is to apply enough fertilizer to the land during the period from picking onions to ambushing, so that the green onions can absorb nutrients well; The second stage is from mid-July to early August, when the prevention and control of insect diseases should be done; The third stage is the period from mid-August to mid-October, when proper topdressing is required and the corresponding fertilizer is sprayed, which can increase the yield.

During the planting period, you should do a good job in land management, and then during the planting period, you must pay attention to water and fertilizer management, water more water on the green onions, and apply more potassium fertilizer to it, so that the planted green onions will be particularly high-yielding.

Attention should be paid to the spacing of planting, and should also be timely watering and fertilization, strengthen the management of water and fertilizer, but also should choose organic fertilizer, and should also be timely loosening of the soil, to ensure that the soil is fertile and transparent, and should also be sprayed in time with some pesticides.

Be sure to fertilize more, and be sure to choose winter when planting, choosing nutrient-rich soils.

The characteristics of green onions are that green onions have wide adaptability to temperature, green onion seedlings can overwinter, and they will not be dormant in hot summer, green onions can be harvested and sold at any time regardless of size, and growers can plant green onions all year round. Plots where green onions are planted should be made of clayey soil or clay soil rich in organic matter. Because the green onion is planted in the soil, the green onion is white and yellowish-white, and the texture is soft and the quality is poor; Although the green onion is white and hard, the yield is low and the quality is poor.

Easy to irrigate and drain. 2 row spacing - generally 75 cm or 80 cm, the depth of the ditch (flat) is not less than 20 cm to the soil (conducive to soil cultivation, increase the length of green onions). 3. After planting, sprinkle pesticides to prevent underground pests and gradually cultivate the soil, not higher than the branch on the green onion.

4. Management of pdyceps control. Green onion is also a relatively common vegetable in China, and it has a high status in the vegetable industry. Let's put it this way, the cultivated area of green onions accounts for 10% of the total area of vegetables, and the production accounts for 7% of the total production.

Well, such an important vegetable, it should not be a problem in terms of cultivation technology, <>

First of all, the ground is tidied up, and then the green onion seedlings are separated according to the size, the large green onion seedlings are planted, and the small ones are planted again. When planting onions, dig the ditch first, and then sprinkle some fertilizer into the ditch (appropriate amount) If there is wheat bran, it is best to sprinkle some wheat bran, green onions, there are sales in the market all year round, in our northeast, the planting area of green onions is more extensive, especially in winter, people have the habit of storing vegetables in winter, green onions are one of the indispensable ones, only winter storage, the number is very amazing.

After the white dew in autumn, plant green onion seeds, must be after white dew, if the white dew is planted before, the green onion will grow green buds in the second year, and the green onion heart will easily become a straight child, and it will soon become old. When planting onion seeds, first planing the soil in the vegetable furrow, and then using special tools to pull the ditch, soil cultivation is an important management measure when planting green onions, it has an important role in preventing lodging, softening false stems, and improving the quality and yield of green onions. Generally, the soil cultivation is carried out many times, starting from the height of the green onion 20 cm, once every half month.

First of all, it is necessary to choose high-quality varieties, and in the process of raising seedlings, it is necessary to choose the right sowing time, which is to strengthen management, and also to choose the soil with relatively high terrain and good drainage, and then we must loosen the soil in time, and there is to mix fertilizer and water in time.

First of all, when planting, we must choose the soil is more fertile and wide land, and use farmhouse fertilizer, do not use fertilizer bought outside, water the plants more, but also to prevent the occurrence of pests and diseases, if there is a situation of small insects, then we must spray insecticides in time.

Sowing time: In order to increase the yield of green onions in the later stage, it is best to choose autumn sowing, the climate is different in the north and south, and the sowing time is best to determine the size of the seedlings before wintering, and the best is to grow to two leaves and one heart. Finishing the seedbed:

Choose a flat, fertile, water-rich plot of land for shallow tillage and fine raking, and then apply sufficient basal fertilizer, in the middle of the 20-25 meters long, 1 meter wide furrow. Sowing: Before sowing, pour enough water in the furrow, wait for the water to penetrate into the soil, stir the seeds with the sandy soil, and sprinkle evenly in the furrow twice.

Green onions are a must-have delicacy and condiment in our lives, many families add a touch of fun to life by planting green onions, so how do we plant green onions correctly in order to get the maximum yield of green onions? Here are some of my tips for growing green onions:

1. Planting green onions generally selects clean and full seeds, the survival rate is high, and the seeds are put into the cultivation soil surface after selection, and then covered with a thin layer of soil, watered thoroughly, and placed in a dark greenhouse for about 2 weeks before germination. Onions like loose and fertile, well-drained soil, can be used to rotten Zen leaf soil, pond mud, river sand, dung according to 2:2:

The ratio of 1:2 is mixed and prepared, and then a small amount of water is poured to keep the soil in a moist state, and finally a small amount of decomposed organic fertilizer can be applied.

2. Sprinkle the germinated seeds into the soil, leave one end of the bud end downward, control the spacing at about 10 cm, cover the surface with 2 cm of thin soil, and water properly to keep the soil moist. 40-50 days after sowing can be transplanted, every 8-10 plants a hole, row spacing 12-20 cm, hole spacing 8-10 cm, shallow should not be deep, 4-6 cm is appropriate, timely watering planting water. It can also be harvested without transplanting after sowing.

3. Green onions like a cooler climate, strong cold tolerance, 13 -20 is the most suitable during the germination period; The best growth period of stems and leaves is 10 -23, and the growth rate will have a significantly higher decline when the temperature exceeds 28.

4. Before and after the emergence of seedlings and after transplanting, the soil can not be dry, it is advisable to water frequently, control watering after seedling 1-3 leaf stage and transplanting seedlings, cultivate loose soil 1-2 times to promote root growth, and generally water once in 7-10 days. If the base fertilizer is applied too little, or the harvest period is too long, it is necessary to top dressing 1-2 times, and apply rotted puffed chicken manure.

5. Generally 60-80 days after sowing or 30 days after transplanting can be harvested, harvesting onions should be carried out in the early morning or evening on a sunny day.

The above are some of my suggestions for planting green onions, I hope it can help you.
